In the Bohr model of an atom (shown), protons are represented in blue, the neutrons are red and the electrons are green. How reactive is the element that this model represents? the answer choices :

a. Highly reactive because the model has two complete electron shells

b. Highly reactive because the model is showing only one valence electron.

c. Non-reactive because the model is showing only one valence electron

d. Non-reactive because the model is showing two complete electron shells

In the Bohr model of an atom,  the element that this model represents is highly reactive because the model is showing only one valence electron.

To ascertain how reactive an element is, we have to look at its valence shell. In the Bohr model, electrons are arranged around the nucleus in shells.

If we look at the model shown, the valence (outermost) shell has only one electron which is easily lost.

This model corresponds to a highly reactive group 1 alkali metal.

Explanation:

Valence electrons are the number of electrons out the outermost shell of the diagram. In this diagram, there is one valence electron. This means that it is highly reactive since the shell is not complete and needs other elements to be able to complete the outermost shell. If this model had a full outermost shell, then it would not be reactive (noble gases).

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
